Question

Help! To solve this system of equations by elimination, what operatfon could be used to eliminate the x-variable and find the value of y?

6x + 5y = 2
4x + 2y = 8
es )
A)
subtract 2 times the second equation from 3 times the first equation
B)
subtract 3 times the second equation from 2 times the first equation
9
subtract 5 times the second equation from 2 times the first equation
D)
subtract 2 times the second equation from 5 times the first equation

Answer 1

c)

subtract 5 times the second equation from 2 times the first equation

Explanation:

subtract 5 times the second equation from 2 times the first equation

This will make the coefficient of the y variable 10

for both equations

10y - 10y = 0

leaving only x
